Abstract
1,189,505. Moulding plastic substances. FURUKAWA DENKI KOGYO K.K. 29 June, 1967 [28 Sept., 1966], No. 30096/67. Heading B5A. [Also in Division C3] A foam is produced by mixing a crystalline olefine polymer or mixture thereof with an organic elastomeric polymer and/or an amorphous organic synthetic resinous polymer, the latter two polymers being miscible with the crystalline polymer and their total amount by weight being not more than that of the crystalline polymer, with an olefine polymer cross-linking agent and a blowing agent whose activation and decomposition temperatures respectively are higher than the melting point of the crystalline polymer, the mixture is moulded into a matrix which is then heated in a gas at 3-50 kg./cm.<SP>2</SP> pressure and at a temperature higher than the activation temperature of the cross-linking agent and the decomposition temperature of the blowing agent whereby a primary expansion is effected and the crystalline olefine polymer is cross-linked. The expanded body is then either (A) cooled below the melting point of the olefine polymer while maintaining the gas pressure, the pressure is released and then the body is reheated to 0-50‹ C. above the melting point, or (B) cooled to 0-50‹ C. above the melting point of the olefine polymer while maintaining the gas pressure which is then released, both procedures resulting in a secondary expansion. Figs. 1 and 2 show an autoclave used to produce the foam and Figs. 3A, 3B and 4 show shaped articles made of the foam.
